Do you have correct POP3/IMAP server address configured in ThunderBird? Reference:

Hello Zhang,
I have been using the same email server in my web browser which is mail.acalschool.com , but with self certified ssl based connection, so I am sure the email server is right, I also replaced it with the IP address, but it didn't work either. For port and authentication, I configured Auto but it didn't work either, I tried it with my other testing domain kidwais.org (the same configuration) and it worked but after allowing the ports through firewall, but in the acalschool.com domain, even after disabling the firewall, I can't connect through thunderbird.
Your kind and prompt help will highly be appreciated.
Thanks
